To all whom it may concern:

Be it known that I, vAL'I'ER Wmorrr, a t'lllZLll of the United States,residin in New York city, in the county of New State of New York, haveinvented certain new and useful Improvements in Combined Type-Writingand Computing Machines, of which the following is a specification.

This invention relates to combined typewriting and computing machines,particularly those which are adapted to do computing in a number ofdifferent columns. This application refers to matter covered in severalprior applications. among which is application No. 543,603, filedjointly by Gustave Degencr and myself, February 12,

1910, and an application of Gustave 0. Degener. No.- 754,709, tiledMarch 17, 1913; also my Patent No. 1.162.730, dated November 30,191. Tothe overlappin subject-mattcr of slwhapplications and t e presentapplication, I make no claim per se, and only intend toclaim in thisapplicatiomsueh combiuatirc relations as the new parts disclosed in thepresent application over such aboveineutioncd applications, combine withthe old features to perform in the aggregate new results.

As herein illustrated, this invention is applied to a combinedtypewriting and computing machine of the IJIXdQI'WOOCl-VI'lght type. inwhichthe carriagcof the typewriter sheet is placed. This platen. as inan or inary typewriter, has a letter-feeding motion and" is arranged insaid motion to control the sma'atim connection between the numeral keysof the typewriter and the computing" wheels of the computing mechanismproper.

For this purpose in said combined ma-.

chine the computing wheels are mounted in a totalizer. and themaster-wheel is connect ed to said carriage to be moved thereby, so

as to engage the computing wheels in said totalizcr sc-riufim. Forcomputing in several columns tabulator stops may be. provided which arearranged to automatically estab lish and let go said connection betweenthe ork and This connection typewriter carriage, and every time thetypewriter carriage carries a stop past said hook, it automaticallycatches the book by means of the stop and thereby causes saidmaster-wheel to be moved by the hook for predetermined distances. A camon the hook may be arranged to ride under a stud and force said hookfree of said stop when beyond any computing zone.

he present invention is illustrated as applied to such a computingmachine having a plurality of totalizers separately connectible to thenumeral keys. For the purpose of varying the nature of the connectionsbetween the numeral keys and the computing wheels, the stops may beprovided with projections, which, in the trayel of the typewriteroarriage, are arranged to shift a.

clutch or clutches in the gearing between said wheels and said keys.Each of these cause the master-wheel to rotate the computingwheel's-sothat they add. in another po sition may rotate them so thatthey subtract, or the clutch may be absolutely neutral, as the case mayrequire. The stops may control each clutch separately by means of camarms hungin the typewriter frame, which arms are drawn by springs toengage said stops as the stops travel with the typewriter carriage.

In order to avoid noise and wear of the parts, and to reduce the amountof shifting of said clutches, the operation of a tabulating key may alsoalways shift any clutch into one selected position and hold, it thereuntil said key is released. As'mostcomputing is in the form of addition,it is convenient to cause a clutch to be always held at its addingposition, unless moved to some other position by the controlling stops.The clutch-controlling arms preferably are in their outermost positionwhen they cause the a clutch is avoided.

Other features and advantages will hereinafter appear. r x

Numeral keys 1 and letter keys 2 of the typewriter de ress levers 3 tocause bell cranks 4 to swing type bars 5 upwardly and rearward] againstthe platen 6, so that type 7 wil write on a work sheet thereon. Saidplaten is mounted in a carriage 8, traveling on rails 9 and 10, and saidcarriage is drawn forward in letter-feeding direction by means of aspring barrel .11, and is controlled in said letter-feed by means of anescapement wheel 12, carrying a ratchet wheel 13 which works in a rack14 connected to the carriage. Said escapement wheel is to controlled bymeans 0f dogs 15 and 16, which dogs are operated by an extension 17 of auniversal member 18, which universal member is operated by heels 19 onthe type bars as they rise toward the laten., 85

arranged to operate the computing mechanism escapement, which is m thenature of an indexing or valuating mechanism acting to cause the numberswritten to be carried into the computing wheels. For this purpose eachnumeral key is engaged by a link 20 (Fig. 2) depending from a bell crank21, which bell crank is'joined by a ,link 22 to the computing escapementproper.

46 When the key 1 is depressed, it draws link 22,

so as to cause the lever 23 to thrust forward a digit determiningjack 24and projects a in 25 from the computing, eseapementor va uating or indexwheel 26. At the same I time a universal disk 27 is drawn backward atthe head of said link 22, so that the lever 28 rocks the link29'controlling a secondary escapement, and said secondary escape'mentcomprises a star-wheel 30, which has been holding the escapement wheel.26 against revolvmg by means of a pin 25 thereon, which had beenpreviously projected.

The escapement wheel 26 constantly tends to be turned by a motor 31through a friction slip clutch, not shown,,bevel gears 32, 33, and ashaft 34, which shaft has fast to it a bevel gear 35, meshing with abevel ear'36; an

s aft carrying turn meshes with a gear wheel 38 fixed to Each numeralkey asit 1s depressed is K said bevel gear 36 is fast on a a gear wheel37, which inthe escapement wheel 26. As the link 29 s moved forward atthe depression of a numeral keg, itlallows the on aging tooth of a seconar escapement w eel 39 fast on the shaft 0 star-wheel 30 to escape est adog 40, so that it strikes a dog 41, an on the return stroke of saidnumeral key, said tooth 39 escapes from the dog 41 and allows theescapement wheel 26 to carry around its pin 25 which hasheen bearinagainst the star-wheel 30, so that sai escapement wheel 26 can turnuntil the pin 25, which has just been pro'ected by the jack 24, strikesthe succee ing tooth of the star wheel 30. Said esca ement wheel 26 isthen held a ainst revo ution by means of a second toot 39 of thesecondar escapement wheel, which has been broug t around to bear againstthe dog 40 when the pin 25 strikes the tooth of the star wheel 30. Asthe motor 31 turns said escapement wheel 26, it turns the bevel gear 42,which is constantly in mesh with the bevel gear 36 and will, throughshaft 43, turn the vertical shaft 44 by means of-bevel rs 45 and 46, andin so doing will cause t e num her then written and computed or indexed,or valuated, by the *escapement wheel 26 to'be carried into a totalizer47. The projected pin 25, which has been previously engaging-thestar-wheel 30, is returned by a cam wiper, not shown herein, after itpasses said wheel.

In the machine herein shown, there are two totalizers 47, which may beidentical and the description of one will answer for both. In each ofsaid totaliizers 47 there is a series of computing wheels 48 (Fig. 3),which are arranged to be engaged seriatz'm by a master-wheel 49 lyingwithin said com- Euting wheels and arranged to becarried ack and forthwithin said wheels to enga e them serv'atim in a manner presently todescribed.

wheel 48. said master-wheel is arranged to be turned by means of asquare shaft 50 on which it is slidably mounted, and said shaft extendsthrough the frame of the machine at 51 where there is fast on it a bevelgear 52, meshes with bevel gears 53 and 54 on shaft 44, and may beclutched to be turned by one of them in a manner to be hereinafterdescribed. Said master-wheel, as will be seen, comprises a hub 55, whichis freely rcvoluble in a sleeve 56, which sleeve, however, moves saidmaster-wheel successively into engagement with the various computinwheels. For so moving it, there is provi ed on the carriage 8 of thetypewriter a rack bar 57 carrying settable lo 58,

which lugs are arranged to successive y enage, as seen in Fig. 5, a hook59 comprising a notch 60 in which said lugs rest when moving it.

When engaged with any computing 110 i Said hook 59 is formed as the endof a sliding-rod or in the casing 62 fast on the typewriting machine.Projecting down wardly from said rod through a slot 63 in the casing, isa pin 64 engaging one arm of a lever 35. which is pivoted between itsends at 66c of which lever the two front arms 67 and 68 engage computingcarriages 69, of which carriages the sleeves 56 controlling the seriatimengagement of the masterwheels form a part. This lever 65, as seen fromthe rear and above in Fig. 4, is normolly drawn to the right by means ofa spring 70 anchored in theframe of the mal5 chine, and in such positionholds the master-wheels 49 in a position to engage the highest\;ll(tl..ifl each of said totalizer's. From such position it'is drawn bymeans of the hook 59, as above described. so that atelach letter-spacemovcment'of the typewriter it moves the master-wheels to engagestep-by-step with the rariouscomput 111 wheels. e

The totalizer 17 comprises a asing 86 (Fig. 3) through a sight opening87 in whi h nmnerals of the dial wheels 88 may brread. Earl] dial wheelis constantly in mesh with an external gear 89 of its computing wheel48. and said computing wheel carries intern l teeth 90, as seen in Fig.3. arranged to he engaged by the teeth 91 of the master-wheel 49. Eachcomputing wheel also is constantly in mesh with a erury-over wheel 912'comprising three different forms of Ieelhf (if these forms ofl'ceth,'onc'set 93 constantly meshes with the gear 89 of the computingwheel 48, so as to turir'isaid wheel when the carry-over wheel is turnedone units space by the computing wheelnext lower in .denomination.

Said projections are of varying dept 'and are arranged toautomatically shift the the clutches 102, 108, which control the turn-10 ing of the computin wheels by means of the numeral keys and t erotation of the carryover mechanism, thus relieving the operator of thenecessit' of manually shifting the handles 104. or this purpose there isour- 7t naled on the casin 128 a shaft 132 carrym a rock arm 133, w ichrock. arm is arranged to cooperate with the upper end done ofthestops..115. When said rock arm 133 rocks to its innermostiposition'eorrespondl0 ing to asubtracting projection or level 130 atthe upperportion of a carriage stop 115, as seen in Fig. 1, it rocks an arm 134fast on said shaft 132, so as'tomove a forwardly extending link 135ivoted on'saidrock arm 8a to swing a bell cra 136 rearwardly, so thatthe arm 137' thereof, which is pivoted by a pin-and-slot connection 138to an extension of the lower handle 104- for the lower total- 'izer,-will shift said handle into its downward l0 position'at the forward endand cause said clutch toconnect the master-wheel to subtract. In asimilar way an outer adding and i0 a stop 115 is arranged to swing on asleeve 140 on said shaft 132, and thereby a pp crank 143 tos'wing itsextension 144 to swing eeve to draw 142, so as to cause its bell the upr handle 104 forthe top totalizer upwa at its forward end and thuscause.

It will be observed that the rock arms 134 and'141 extend in oppositedirections, and

to ofiset this, the bell cranks 136 and 143-105 are setto work inopposite directions, so that identical rojections or levels of the aveidentical effect on both roc am 133 and rock arm 139. Each of saidro'ckarms 133 and 189 is drawn by a s'p'riiig-145 'ina forward directionconstantly tending to move it to cause the computing mechanism to'subtract.-

In order to enable the typewriter'carriage to feed past theflat faces146 ,and'14-7 of rock arms 133 and 189 respectively the endsthereofare'beveled as at 148 to orm cam surfaceswhich will force saidarms outwardly when the stops strike'them. Each flat face 146, 147 is ofthe ,widthof the com- :puti'ng column or zoneso as to ho d the .clutches,33 in geition throughout e colman or some. aclrof the rock arms 133 and139is formed where it is fast onto its ,shaftor sleeve respectively,comparatively 12s narrow, so that the two portions thereof where fast totheir shaft and sleevewill nottalre up more than the column" over whichT affect the com ntin mechanism.

k arm 139 is orme the right and then upwardly lugs carried by said stopswith a narrow ortion 149 and then at the top is extended broadly so thatthe ed e 14.7 is of length equal to a computing co umn. The rock arm 133is formed with a narrow portion 150, which then extends to at 151, andthen to the left at 152, so that the edge 146 will be of precisely thesame len th as ed e 147, and precisely above it. In t 13 we t e.

two rock arms 138and 139 swing per ectly clear of each other, andoperate on the same column. The rockarm 133 in its narrow portion isbent outwardly at 153, so that the narrower portions 149 and 150 neartheir tops will lie in the same plane when not engaging stops 115.

Whenever a tabulating key 117 is depressed, these rock arms 133 and 139are automatically swung outwardly so as to be practically clear of thestops 115. For this purpose, the rock shaft 123, which operates thecarriage release mechanism, carries also a rock arm 154 fast thereon,which strikes the tail of a lever 155, the up er end of which has abroad-edge 156, and when the rock shaft 123 is swung by the depressionof any tabulating key, the rock arm 1-54 will swing the flat surface ofthe lever 156 against the rock arms 133 and 139 and swing themoutwardly. Owing to a little lost motion in the clutches, these rockarms 133 and 139 can be swung completely clear of the stops 115, andthus the carriage may travel unimpeded by the edges 146 and 147 of saidrock arms.

he stops 115 may include any, desired combination of adding, subtractingand new tral positions, such as are shown m Fig. 9. The rock arms 133and 139 are locked to their carrying. members bymeans of set screws 157and 158, so that they may be adjusted thereon, and the lever 155 ispivoted as a sleeve outside of the sleeve 140 and may be'held againstthe frame 128 by means of a pin 159 fast on the sleeve 140,

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others. llnving thusdescribed my invention, I claim: 1 I.
